Backend Engineer

ABOUT THE ROLE

TellySynco (by FamSync) is a family coordination dashboard that runs on Apple TV — a shared command centre for busy households. We're building a tvOS-first product with an iOS companion app, targeting the 35M+ US households that already own Apple TV.

We need a Backend Engineer to own the entire server-side infrastructure: REST APIs, real-time

sync, calendar integrations, and background workers. You'll work directly with the founder and have full ownership of backend architecture from day one.

WHAT YOU'LL BUILD

REST API

Auth, household management, tasks, calendars, meals, shopping, and photos — clean, well-

documented endpoints consumed by tvOS and iOS clients.

Real-Time Sync

WebSocket server with Redis pub/sub. Target: sub-3-second sync latency across all family devices so the TV always reflects live household state.

Calendar Integrations

Direct OAuth 2.0 integrations with Google Calendar, Microsoft Outlook, and iCloud CalDAV.

Webhook handling, token refresh, and event normalisation to a unified internal schema.

Background Workers

Calendar polling and sync jobs, push notification dispatch via APNs, RevenueCat subscription webhook processing, and scheduled reminders.

TECH STACK

Runtime - Node.js 20+, TypeScript

Framework - Fastify (preferred) or Express

Database - PostgreSQL 15+ with Prisma ORM

Cache / Queue - Redis 7+, Bull for job queues

Storage - AWS S3 or Cloudflare R2

Push - Apple Push Notification Service (APNs)

Subscriptions - RevenueCat webhooks

Deployment - Railway (primary) or AWS

Observability - Sentry

TECHNICAL REQUIREMENTS

Must Have

• 3–5 years of backend development experience

• Strong Node.js and TypeScript proficiency

• PostgreSQL — schema design, indexing, query optimisation

• REST API development with Express or Fastify

• OAuth 2.0 implementation experience (any major provider)

• WebSocket or real-time communication systems

• Redis — caching and pub/sub patterns

Nice to Have

• Google Calendar API or Microsoft Graph API experience

• Apple Push Notification Service (APNs)

• Deployment on Railway, AWS, or GCP

• Prisma ORM

• LLM API integration (OpenAI, Anthropic, or similar)

CTC: INR 8-12 lpa (based on experience)

WHY JOIN FAMSYNC

• Own the backend from day one — greenfield, no legacy constraints

• Modern stack: TypeScript, Fastify, Prisma, Redis

• Interesting technical challenges: calendar sync, real-time WebSocket, multi-platform OAuth

• Work directly with the founder, not through layers of management

• Equity conversation for the right candidate
